Disposable email checker
Enter an address or a domain to see whether it is a throwaway inbox from a temp-mail service. Nothing is sent to the address and nothing is stored.
How to read the result
Disposable: the domain is on the list, is a subdomain of a listed one, or its mail goes to a known temp-mail service. Mail to it will bounce once the inbox expires. Not disposable: neither matched; it says nothing about whether the address itself exists.
To check everything else about one address, format, mail servers, role addresses and typos, use the email verifier.
Questions
- How does it detect disposable email?
- Two ways. The domain is compared with a list of 10,123 known throwaway domains (the community list at github.com/disposable-email-domains), including subdomains of them. Then its mail servers are compared with those of known temp-mail services, which catches new domains before any list does.
- How often is the list updated?
- About monthly; this copy is from 2026-11-03. The mail-server check covers domains registered since.
- Should I block disposable emails on sign-up?
- For a product that sends real email after sign-up, usually yes: the inbox expires, later mail bounces, and bounces hurt your sender reputation. Show a clear message asking for another address rather than failing silently.
- Is Apple Hide My Email disposable?
- No. Addresses at privaterelay.appleid.com forward to a real inbox the person keeps; this checker does not flag them.
